Liquid pipe: copper pipe (for R410A) external diameter: 5/8 inch; thickness: 1.0 mm;
pressure tolerance range: ≥ 4.5 MPa.
Gas pipe: copper pipe (for R410A) external diameter: 7/8 inch; thickness: 1.2 mm;
pressure tolerance range: ≥ 4.5 MPa.
Thermal insulation foam: thickness ≥ 13 mm.
Oil traps and inverted traps: To ensure the NetCol5000-A reliability, make an oil trap
every 5 m to 6 m along pipes in the vertical direction and make an inverted trap
respectively at the intake vent and exhaust vent of the outdoor unit.
